Embodiment 1
[0035] Use a PVC square diaphragm electrolyzer, the volume of the anode chamber is 10×10×5cm 3 , the volume of the cathode chamber is 10×10×2cm 3 , the diaphragm is an effective area of 7 × 12cm 2 perfluorinated cationic membrane. The anode is 32 layers with an effective apparent area of 40cm 2 30 mesh ordinary braided iron mesh (wire diameter d = 0.14mm), the effective apparent area of the cathode is 40cm 2 nickel foam. The anolyte volume is 200ml, and the catholyte volume is 100ml. Both anolyte and catholyte are 13M KOH solution. Add 2.5ml additive solution to the anolyte, CuCl in the additive solution 2 、KIO 3 、Na 2 SiO 3 The concentrations of , KI, and KOH are 0.015M, 0.015M, 0.3M, 0.015M, and 5M, respectively. The electrolytic cell was placed in a constant temperature water bath with an initial temperature of 60°C, and the temperature stabilized at 65°C after the current was applied for about half an hour. Vigorously stir the anolyte with an electric stir...
Embodiment 2
[0037] The K obtained by the method described in Example 1 with a purity of 95% 2 FeO 4 20 g of the solid was dissolved in 200 ml of 7M NaOH solution under ice-bath conditions. After vacuum filtration through a sand core funnel, the concentration of ferrate in the filtrate was determined to be 0.47M by the chromate method. Under the condition of ice bath, 20mL of filtrate and 10mL of saturated KOH were successively mixed in the same suction filter bottle through a sand core funnel, and reacted for 2 to 3min to make a mixture containing solid K 2 FeO 4 Seed mother liquor. Under the condition of magnetic stirring, add the remaining 180mL filtrate and 90mL saturated KOH solution alternately into the suction filtration flask at the speed of 5-8mL / min and 2.5-4mL / min respectively, keep the solution temperature below 20°C, and the whole feeding process is at 20°C. Complete within ~30min, then continue to stir for 5min. The K obtained from the reaction in the suction filter flask...

The anode is 32 layers with an effective apparent area of 40cm 2 30 mesh ordinary braided iron mesh (wire diameter d = 0.14mm), the effective apparent area of the cathode is 40cm 2 nickel foam. The anolyte volume is 200ml, and the catholyte volume is 100ml. Both anolyte and catholyte are 13M KOH solution. Add 2.5ml additive solution to the anolyte, CuCl in the additive solution 2 、KIO 3 、Na 2 SiO 3 The concentrations of , KI, and KOH are 0.015M, 0.015M, 0.3M, 0.015M, and 5M, respectively. The electrolytic cell is placed in a constant temperature water bath, the initial temperature is 60°C, and the temperature stabilizes at 66°C after the current is applied for about half an hour. Vigorously stir the anolyte with an electric stirrer, el...
